How many moles are in 14.35 x 1022 molecules of H3PO4?

0.24mole

Explanation:

Given parameters:

Number of molecules  = 14.35 x 10²² molecules;

       Unknown = number of moles of H₃PO₄

 A mole of a substance is the quantity of matter that contains the avogadro's number of particles.

 This number is given as 6.02 x 10²³ particles. The particles can be atoms, molecules, protons, electrons e.t.c

          6.02 x 10²³ molecules is contained in 1 mole of any substance

          14.35 x 10²² molecules will contain:     = 0.24mole
